A Spatial Data Model for Moving Object Databases

A Spatial Data Model for Moving Object Databases

Moving Object Databases will have significant role in Geospatial Information Systems as they allow users to model continuous movements of entities in the databases and perform spatio-temporal analysis. For representing and querying moving objects, an algebra with a comprehensive framework of User Defined Types together with a set of functions on those types is needed. Moreover, concerning real ...

Object-oriented data modelling for spatial databases

Data modelling is a critical stage of database design. Recent research has focused upon object-oriented data modes, which appear more appropriate for certain applications than either the traditional relational model or the entity-relationship approach. The object-oriented approach has proved to be especially fruitful in application areas, such as the design of geographical information systems w...

A Topological Data Model for Spatial Databases

There is a growing demand for engineering applications which need a sophisticated treatment of geometric properties. Implementations of Euclidian geometry, commonly used in current commercial Geographic Information Systems and CAD/CAM, are impeded by the finiteness of computers and their numbering systems. To overcome these deficiencies a spatial data model is proposed which is based upon the m...

A P2P Meta-index for Spatio-temporal Moving Object Databases

In this paper we propose a distributed meta-index using a peer-to-peer protocol to allow spatio-temporal queries of moving objects on a large set of distributed database servers. We present distribution and fault tolerance strategies of a meta-index that combines partial trace of object movements with aggregated data about the number of objects in the database servers. The degrees of distributi...
